FASTENING DEVICE FOR VEHlCLE-HUBS.

SPECIFICATION forming part of Letters Patent No. 336,520, dated February16, 1886. Application filed December 2, 1885. Serial No. 184,521. (Nomoalcl.)

To all whom, t may concern: to prevent the escape of oil or the entranceof Be it known that I, CHARLES ANTHONY dust or sand.

JOHNSON, a subject of the King ofNorway and In Figs. 7 and8 sonie slightniodilications of Sweden, who have declared inyintention of betheconstruction are shown.

5 coming a citizen of the United States, residing In Fig. 1 the twoparts B B2 of the ferrule 55 at St. Paul, Ramsey county, Minnesota, haveare shown in one single piece of metal, while invented certain new anduseful Improvements in Figs. 7 and 8 the part B-2 is shown formed in inVehicle-Hubs, of which the following is a a separate piece and screwedinto the part B. specification. In Fig. 7 the part B2 is shown extendingonly ro In the drawings, Figure l. is a sectional view to the outer endof the nut C, while in Fig. 8 60 through the hub Ofa wheellongitudinally. the part B2 is shown extending to the rear of Fig. 2 isacross-section on the line ma of Fig. l. the nut, so that the latterrevolves in the part Fig. 3 is a crosssectional view on the line y y B,instead of in the ferrule, as in Figs. l and of Fig. l.

Figs. 5 and 6 reprearesubstantially the saine in all three of the 65 sent detached perspectiveViews of the differforms shown. ent parts of the nut-locking mechanism.Figs. It the construction shown in Fig. 1 is used,

The disk d2 ter having the usual collar, a', andscrew-th read will then be revolved until the'hexagonal plate a2, whilethe hub is provided with the skein e2 is set into the cavity in the nutC, as shown b. On the outer end of the hub A is secured in Fig. 7, whichwill firmly x and hold the 75 a ferrule, B', in which a cylindrical nut,C, is nut in the ferrule, and consequently hold the adapted to run, thenut fitting upon the screw nutixed into the hub, so that the wheel, whenend a2 of the axle A3, as shown. The t'errule placed upon theaxlejournal and revolved,

The disk d2 8o stud having a milled edgeddisk, d2, outside is then turned backward, which will run the theferrule, by which it may be turned from the hexagonal disk el out of thecavity in the nut Outside. The stud d is provided with an in- C, as inFig. l, so that the hub is left free to ternal screw-thread, in which ascrew-stud, e', revolve around the nut and axle-journal, the

Then when it is desired to remove t onal plate tobe moved inward and outward tothe wheel to oil the axle-journal or forany ward and away from the cylindrical nut G, as other purposes, it isonly necessary to set the required. The outer end of the cylindricaldisk e2 into the cavityin the nut C by turning 4o nut is provided with acavity corresponding to the disk d2 and then revolving the wheel back-9o the hexagonal disk e2, so that when the stud ward to run thescrew-thread@2 out of the nut d is revolved by the disk d2 in onedirection, C. The wheel may then be laid down on one the disk e2 will beforced into the cavity in the side and a quantity of oil poured into thehub, nut, and thus lock the nut fast to the ferrnle, and the wheelreplaced on the axle-journal, as

One greatadvantage of this arrange- 95 of the disk e2, being hexagonal tocorrespond ment is that no oil can escape from the outer therewith. endof the hub to soil the clothing of the per- A rubber washer, g, will beinserted between son getting into or out of the vehicle, or being thestud d and the outer ends, B2, ofthe ferrule wasted by running out ofthe hub.

5o to form a packing between the stud and felrule I have shown the platee2 hexagonal 5 but I 1GO do not wish to be confined to that preciseform, as I am aware that almost any irregular form of disk may be used.Y

In Fig. 8 the screwstud e is shown on the stud d', while the internalscrew-thread into which it fits is shown in the disk e2, instead of inthe stud d; but the functions and mode of operation are the same in bothconstructions.

Having thus described my invention, what I claim as new is- 1. In avehicle-Wheel, the combi'nationmith the axle-journal A3, hub A', and nutC, of a ferrule, B B2, supporting an irregular disk or plate, e2,adapted to be connected to and disconnected from said nut from outsidesaid ferrule, substantially as set forth.

2. The combination of hub A', axle-journal A3, nut C, having irregularcavity in its outer end, ferrule B B2, disk e2, having irregularperiphery corresponding to the irregular cavity in said nut, stud d',journaled in said ferrule B B2, and means, substantially as described,whereby the revolution of said stud will cause said disk e2 to beconnected to or disconnected from said nut O.

In testimony whereof I have hereunto set mv hand in the presence of twosubscribing witnesses. v n
